Inclusive decays from lattice QCD: computational strategy and a first physical result
Alessandro De Santis, Antonio Evangelista, Gael Finauri +16
We present a strategy to compute the inclusive decay rate for the process from first principles in lattice QCD. The physical decay rate i…
Heavy quark thermodynamics with anisotropic lattices
Jon-Ivar Skullerud, Rachel Horohan D'Arcy, Gert Aarts +11
We present recent results from the FASTSUM collaboration, using anisotropic lattice QCD to study spectral properties of heavy quarkonia and open heavy flavour systems at high tempe…
On the effective restoration of symmetry at finite temperature
Gert Aarts, Chris Allton, Ryan Bignell +4
The symmetry of the massless QCD Lagrangian is explicitly broken by the axial anomaly, but it may be effectively restored at finite temperature. Determining the temperatur…
symmetry restoration at finite temperature with mesonic correlators
Ryan Bignell, Gert Aarts, Chris Allton +4
The symmetry of the massless QCD Lagrangian is explicitly broken in the quantised theory by the anomaly. It may be effectively restored at some finite temperature, which w…
Thermal evolution of dark matter and gravitational-wave production in the early universe from a symplectic glueball model
Mattia Bruno, Niccolò Forzano, Marco Panero +1
The hypothesis that dark matter could be a bound state of a strongly coupled non-Abelian gauge theory is theoretically appealing and has a variety of interesting phenomenological i…
The curvature of the pseudo-critical line in the QCD phase diagram from mesonic lattice correlation functions
Antonio Smecca, Gert Aarts, Chris Allton +6
In the QCD phase diagram, the dependence of the pseudo-critical temperature, , on the baryon chemical potential, , is of fundamental interest. The variation of $…
